Inductive charging means you'll never have to plug your phone in again, and to avoid clunky add-on solutions if your device doesn't have it built in, Duracell has created this wafer thin adapter card that slips in alongside its battery.

There is a catch, though. It's only designed to work with phones that comply with the Power Matters Alliance's Wireless Charging Card specification. So OEMs will need to include a compatible connector where the battery interfaces with the phone, to facilitate charging, but also data transfer as the Duracell Powermat WiCC card doubles as an NFC antenna. You'll also need a phone with easy access to the battery obviously.

So while you won't be finding them at your local Best Buy anytime soon, it's another important step towards inductive wireless charging becoming more ubiquitous across devices. [Engadget]
